Securing Your Structure(s):
Step 1- Foundation
Find out if your house is bolted to its foundation. If your house was built after 1935, chances are it is. If your home is older, you can have your house inspected and install bolts if necessary.
Step 2 - Chimney
Make sure your chimney is soundly attached to the structure of your home. Collapsing chimneys are one extremely dangerous outcome of an earthquake. If your home was built before 1960, you may have to have it reinforced.
